Abstract
We present the results of numerical simulation of the thermal regimes of hot water pipes under flooding conditions with account for evaporation and diffusion of steam in a wetted thermal insulation. The extents of heat losses by hot water pipes under these conditions have been revealed. The contributions of evaporation and steam diffusion effects to the total heat losses are shown. The necessity of taking into account the nonstationarity of transfer processes and of the values of volume fractions of moisture and steam in the structure of a wetted thermal insulation layer in modeling thermal regimes of hot water pipes under flooding conditions has been proven.
